HYDRAULIC COUPLING.4

SFECIFIGATIGN forming' part Of Letters Patent No. 679,005, dated July 23, 1901.

Application filed August 15, 1899.

To all whom, it 'muy concern,.-

Be it known that I, THEODORE C. PROUTY, a citizen of the United States, and a resident of Midland, county of Midland, and State of Michigan, have invented a new and useful Improvement in Hydraulic Couplings, of which the following is a specification, the principle of the invention being herein explained and the best mode in which I have contemplated applying that principle, so as to distinguish it from other inventions.

The object of my invention is to provide a chesp and effective couplingr for hydraulic connections; and it consistsof means hereinafter fully described. I

The annexed drawings and the following description set forth in detail certain mechanism embodying the invention, such disclosed means constituting but one of various mechanical forms in which the principle of the invention may be used.

In said annexed drawings, Figure I represent-s a partial longitudinal sectional view of the-male member of my improved coupling. Fig. Il represents a partial longitudinal section of the female member of my improved coupling. Fig. III represents a longitudinal section of the two members of the coupling connected. Fig. IV represents a-detail perspective view of the improved packingin my invention, illustrating its form before being inserted in the female member; and Fig. V represents a central longitudinal section of said packing.

The male member A consists of a nipple a,

provided with two-lugs a', disposed diametrlcally oppositeench other, and an internallythrended portion a, adapted to be secured to a faucet or other threaded hydraulic duct. Said threaded portion may be replaced by any form of connection whereby the nipple may be secured to the desired water connection.

The female portion of the couplingconsists of a tube B, provided with an interior groove b, in 'which'is locnted a pecking-ring B' of U- shaped cross-section in s manner such that the two portions of such section extend in the direction of the coupling exis, the open portion of such section being farthest removed from the coupled end of such female member. Said female member is further Serial No. 727,254. (Nn model.)

provided with a portion b', which may be secured to the desired duct and which may be replaced by a thrended portion, such cs is shown in the male member.

The coupled end of the female member is provided with engle-slots b2, located diametrically opposite each other, which are adapted to receive the lugs a., formed on the nipple of the male member of the coupling, which may hence be securedl against lateral displacement.

Ihave provided s. one-piece female member, which not only has formed thereon its portion of the connecting means, (the angleslots 192,) but also has the internal groove b of a. fixed width, so that when the packingring is inserted it is held immovable in so far ns movement longitudinally of the coupling is concerned. Owing to this construction, the movement by which the male and female members are coupled and uncoupled can not under any circumstances change the position or shape of the ring, such as would occur in onse one of the end wells of the groove was formed by a removable portion of the female member, especially if said removable portion formed part of the coupling means. In the latter case accidental binding of the parts, dsc., would in uncoupling release the removable portion and nllow of a change in position and shape .of the ring in an obvious manner.

Thediameter ofthe nipple of the mele member is made substantially equal to that of the inner diameter of the packing-ring.

passing through the joint so formed in trying to escape through the interstices formed by such connection pass into and between the two folded portions of the packing, whereby the latter is expanded against the outer surface of the nipple of the male member and the inner adjacent surface of the female member, thereby eitectually' scaling the connection against leakage.

flexible material used for packing purposes, and in being inserted into the femnle memorder to be placed with facility in the groove b.

'lhe above construction permits the formution of this connection without rcducingtho When the two members are secured, fluid' The packing-ring B' is made of uny desired.

ber is doubled up, as shown in Fig. IV, in'

cross-sectional aren of the duct in which said ioint is formed :ind even permits the dinmcicr of the pitching lo he slightly grenier than the diameter of the male member, thereby permittingr the hitler to he easily inserted even in crises where obstructions in the form of refuse or other matter may have found its way upon the inner surfnce of the packing.

Other modes oi' .-ipplying,r the principle of my invention maybe employed instead of the one explained, chungo being made as regards the mechnnism herein disclosed, provided tlre means covered by :my one of the following claims be employed.

The groeve in the female member is formed contiguous to the interior of one extremity and is provided, ns shown, with two transverse end surf-.tees distant from each other substantially the width of the packing-ring, whereby it is seen that the'said ring is confined laterally in both directions of the coupling-axis, and hence cannot become displaced when the two members are coupled and isalso securely confined in the female member when the two members ere uncoupled, there# by preventing the loss of the ring and consequent inconvenience which would be occasioned thereby.

I therefore particularly point ont and distinctly claim as my invention- 1. Inahydrauliccoupling, the combination with a male, of a one-piece female member removably secured thereto, said female member being form'ed with nn annular groove permanent as to size lfind position on the interior of one extremity and provided with a packing-ringr located in said groove, said malemember projecting into and engaging the inner surface of said ring, suhstz'intinlly ns set forth.

2. In ahydranlic coupling, the combination with a male, of a one-piece female member removably secured thereto, seid female member having an interiorgroove permanent ns to size and position contiguous to one end opening: and provided with n packing-ring in seid groove, said mele lnember fitting loosely in said opening und projecting,r into and interiorly engaging said ring, substantially as set forth.

3. In ahydraulic coupling, the combination with annale, of a one-piece female member re.-
